The Climate Prediction Center has issued a La Niña Advisory. LSU Health Climatologist Barry Keim says the advisory means La Niña conditions are present and expected to continue. Keim says when there is a La Niña, the tropics are more conducive for storm development.
“As we get into the backend of the season with this La Niña kicking in, that could reduce the amount of wind shear. We could have a, not a real busy back half of the season, but busier than normal,” Keim said.
Keim says a La Niña also means we could see less precipitation this winter.
“La Niña winters are typically warmer and drier than normal. What happens is the jet stream gets deflected further to the north, more across the middle part of the country, across the Midwest,” Keim explained.
Keim says this is expected to be a weak La Niña, but still have an impact on our weather.
“It’ll be a short-lived event. It’ll be a relatively weak event, but the implications are still pretty huge. Especially when we start talking about adding storms to the backend of the hurricane season. I hope that doesn’t happen,” Keim said.
